Answer:
A. 8 3/4 degrees
Step-by-step explanation:
Alaska temperature dropped from 3 degrees Fahrenheit to twelve and a quarter degrees Fahrenheit below zero
12 1/4°F - 3°F
=8 3/4°F
The temperature dropped by 8 3/4°F
(secx + tanx)^2

2tanxtanx + 1 + 2secxtanx <span>
The expression (secx + tanx)2 is the same as </span>1 + 2tan2x + 2secx tanx. The answer is letter D.
Answer:
x=2 and y=0 is the required result.
Step-by-step explanation:
We have been given system of equations:
(1)
And (2)
We will use elimination method:
Multiply 1st equation by 3 and 2nd equation by 5 we get:
(3)
(4)
Now subtract (4) from (3) we get:
Now, put y=0 in (1) equation:
Hence, x=2 and y=0
